Went on vacation and played with my kid in the pool on Thursday afternoon. Shortly after the watch started constantly prompting me to "power off? yes/no." I tried a few different things (soft reset, hard reset, letting it die and charging it back up, etc..) but every time I turn it on it reverts to 9:35 AM on Thursday. Will stay on 2 or 3 minutes and then prompt me to power off.
I suspect it is toast but thought I would put this out there and see if there were any solutions.
